Base64 Module
Preface
Yesterday the team's sister came to ask questions about the POP3 protocol, so today a little bit about the format of the POP3 protocol and the poplib in Python. And the POP server back to the data in a part of the need to use
Python uses the base64 module for binary data encoding.
Preface
Yesterday, my team asked me about the POP3 protocol. So today I have studied the POP3 protocol format and the poplib in Python. Some of the data transmitted back by the POP server needs
Brief introductionFeatures: RFC 3548:base16, BASE32, Base64 data encoding. Converts the binary data to an ASCII sequence that is suitable for plaintext protocol transmission. Transformation8bits contains valid data for 6, 5, or 4bits for each byte,
BASE64 encoding algorithm of Android Data encryption preface:In front of the study summed up the usual development encountered in various data encryption methods, the end will be encrypted binary data Base64 encoding, play a two times the effect of
The previous study summed up the usual development of the various data encryption methods, the final will be encrypted binary data for BASE64 encoding, played a two times encryption effect, in fact, Base64 from the strict sense is not a
Objective:In front of the study summed up the usual development encountered in various data encryption methods, the end will be encrypted binary data Base64 encoding, play a two times the effect of encryption, in fact, Base64 from the strict sense
Base64 Is based on 64 Printable characters to represent the representation of binary data. Because 26 = 64 , So every 6 It is a unit that corresponds to a printable character. Three bytes in total 24 Bit, corresponding 4 Items Base64 Unit, that is 3
Python uses the base64 module to process base64 encoding.
The base64 module is used for base64 encoding and decoding. This encoding method is very common in email.It can encode binary data that cannot be displayed as text information to be displayed.
Base64 is one of the most common encoding methods for transmitting 8Bit bytes of code on the network, and you can view rfc2045~rfc2049, which has a detailed specification of MIME. BASE64 encoding can be used to pass longer identity information in an
Base64 encoding. First, we should clarify why there is a 64 character in it? In fact, because the encoding uses 64 plain text to encode arbitrary binary files, it only uses the A-Z, A-Z, 0-9, +,/This 64 characters, some people who have "a little
